Another month, another update. This one is less of a "big feature" upgrade, and more of a "let's make this one the most stable and bug-free release yet". That said, there's bound to be something useful in here regardless of what you're working on.

My fingers are crossed there are no teething problems, but please alert me if anything crops up. And as always, back up before upgrading.

Ultimate FPSUltimate FPS has come on leaps and bounds over the past few months, and recent updates have also made it possible for a much more reliable integration with AC. v1.43 requires that you use UFPS v1.4.9 or later, and you'll have to adjust your Player prefabs to suit the code changes - but the process of creating an AC/UFPS player prefab is now incredibly simple. See this tutorial for full instructions, or just download the updated ready-made prefabs to make use of right away.

Tutorial videosWith AC's rapid development and changes over the past months, tutorials have been nearly all text-based so that they can be updated. But now that AC's reaching a point of maturity, it's high time it got some new video tutorials to guide people through the process of creating a game from scratch. So, grab a beverage and make yourself comfy - you've got FIVE HOURS of training to enjoy:

Creating a 2D gameWith a running time of 90 minutes, this back-to-basics tutorial covers all the essentials needed to make a 2D game. Navigation, Hotspots, NPCs, Inventory, Variables and more are all covered in detail, so even if you're more interested in 3D, this is a good place to start.

Creating a 3D gameWeighing in at over three-and-a-half hours, this more advanced tutorial goes beyond the basic workflow to cover some of the more complex features of AC. Make use of parameters, Active inputs, lip-syncing and custom UIs to build a fun game designed especially for the video. Get all you need by downloading the Evil Lair asset files! (Note: currently, the assets are intended for Unity 5.)

Speech Manager improvementsThe somewhat-neglected Speech Manager has been given some much-need attention, and has some handy new features for voiced and/or multi-language games. Gathered text can now be filtered by type, scene or description, and each line can be selected to bring up info like translations and expected audio filenames.

Unity 5AC now has an official Unity 5 release, and Unity 5 users (and Unity 4 Pro) can now take advantage of a few extra features. If your Characters are Humanoid Mecanim types, you can rely on automatic IK head-turning. And the new "Engine: Play movie clip" does what you'd expect - though frankly it was just an excuse to have a script file called "ActionMovie"..

It's working great so far, bravo. One little thing I've found. When I choose Character: Hold Object, all of the other actions below disappear in the Inspector. When I toggle the arrow closed, they show up all collapsed. Then, when I hit the arrow to expand them all, they disappear again.

I get the same error, but so far as I can tell it doesn't affect the gather process. The line of code causing the error simply saves the scene - it may be a Unity bug, but I don't believe it's a problem.

So far as the Submit and Cancel buttons go, I removed them because they aren't AC-specific. Do you need them for something else? It's possible to opt out of overwriting your Inputs and References file (the one that stores the active managers) when upgrading to make the process easier.

@hedgefield: I've only ever tested from release to release - never skipping any. The main thing is that you keep in mind the upgrade notes for each one, which assume you're upgrading from the previous release. Just back it up, first.
